Background: In observational studies, older adults with insufficient or deficient serum vitamin D levels are at higher risk of cardiovascular disease (CVD), but randomized trials have failed to demonstrate reduction in CVD risk from vitamin D supplem

ObjectiveDue to the long prodromal period for dementia pathology, approaches are needed to detect cases before clinically recognizable symptoms are apparent, by which time it is likely too late to intervene. This study contrasted two theoretically-ba

Background: There is inconsistent evidence on the optimal time after standing to assess orthostatic hypotension (OH). Objectives: To characterize the timing of OH after standing in older adults and the fall risk associated with OH at specific times.

The benefits of routine engagement in physical activity (PA) on vascular health are well established; lesser known is whether vascular health associates with accelerometry-based daily patterns of PA in mid-to-late life. Using linear regression models

This study hypothesized that perceived fatigability, fatigue standardized to walking, would better discriminate mortality risk than general fatigue symptoms. We leveraged perceived fatigability, self-reported tiredness, self-reported low energy and m

Researchers often prefer different accelerometers for measurement of sleep and physical activity (PA) in older adults, but wearing multiple accelerometers increases costs and participant burden. We tested the hypothesis that the Actiwatch-2, commonly

Age-related sensory impairment, such as loss in vision or hearing, have been linked to poor brain health. Yet, the relationship between co-occurring sensory impairments and brain volumes remains unclear. We used cross-sectional sensory and brain imag

The Apolipoprotein-ε4 (APOE-ε4) genotype is associated with earlier onset and greater risk of β-amyloid deposition, but whether APOE-ε4 status is associated with physical activity amount or fragmentation remains unclear. In 563 BLSA participants

Physical activity and sleep are well-established predictors of health and longevity with aging. Wrist accelerometers, that produce high-frequency time series data, capture multiple aspects of daily physical activity and sleep 24-hours/day. Historical
